Your service looks good! I ended up having to get a friend to help me. He found out how the nav items are identified. The items I wanted to highlight were the 8th and 9th items in the nav bar respectively. Below is the CSS:
#main-navigation ul li:nth-child(8n) a,
#main-navigation ul li:nth-child(9n) a
{
background-color: #EA0437 !important;
color: #ffffff !important;
padding: 10px !important;
-moz-border-radius: 5px !important;
-webkit-border-radius: 5px !important;
border-radius: 5px !important;
-moz-transition: all 150ms linear !important;
-webkit-transition: all 150ms linear !impo
